He whāinga nui te maimoatanga waipara ahumahi kore tukunga i roto i te ao tiaki taiao, mā roto i ngā tikanga hangarau hei whakatutuki i te maimoatanga whai hua o te waipara me te whakamahinga rauemi, hei whakaiti i te parahanga taiao, he mea nui te tiaki i ngā rauemi wai. Ka whakaurua e au ētahi ara hangarau maimoatanga waipara ahumahi kore tukunga nui.
Tuatahi, ko te hangarau maimoatanga ā-tinana tētahi o ngā huarahi nui hei whakatutuki i te maimoatanga waipara ā-umanga kore tukunga. I roto i ēnei, ko te hangarau wehenga kiriuhi he tikanga maimoatanga ā-tinana whai hua, he penapena pūngao hoki. Mā te whakamahi i ngā rauemi kiriuhi he rerekē te rahi o ngā pore, ka wehea pai ngā matū kino me ngā katote konganuku taumaha i roto i te waipara kia tutuki ai te kaupapa o te purenga wai. Ko te hangarau tātari kiriuhi-rua, arā, ko te tukanga o te whakakotahi i te kiriuhi tātari-rahi me te kiriuhi osmosis whakamuri, tētahi o ngā tono nui o te hangarau wehenga kiriuhi. Ka taea e tēnei hangarau te whakatutuki i te tātari hohonu maha o te waipara, te tango i ngā wāhanga kino, me te hangarua tika i te waipara kia kore ai e tukunga.
Tuarua, he huarahi nui anō hoki te hangarau maimoatanga matū hei whakatutuki i te maimoatanga waipara ā-umanga kore tukunga. Ka hurihia e te hangarau redox ngā poke i roto i te waipara hei matū kore-paitini, kore-kino hoki mā roto i ngā tauhohenga matū, ā, ka tutuki te maimoatanga hohonu o te waipara. Ka taea e ngā hangarau whakapūngao matatau, pērā i te whakapūngao Fenton me te whakapūngao ozone, te tango pai i ngā mea waro uaua-ki-te-pirau i roto i te waipara me te whakapai ake i te matū koiora o te waipara. Hei tāpiri, ko te tikanga matū whakapūngao, te tikanga whakawhiti katote, me ētahi atu, he hangarau maimoatanga matū e whakamahia whānuitia ana, ka taea te tango i ngā katote konganuku taumaha me ngā mea iri i roto i te waipara.
He wāhanga nui te hangarau maimoatanga koiora o te maimoatanga waipara ā-umanga kore tukunga. Ka whakamahia e te hangarau maimoatanga koiora te pākia o ngā moroiti ki te pirau me te whakaputa ke i ngā matū waro i roto i te waipara. Ko ngā hangarau maimoatanga koiora noa ko te paru whakahohe, te kiriata koiora, me te nakunaku anaerobic. Ka taea e ēnei hangarau te tango pai i ngā poke waro i roto i te waipara, te whakaiti i te hiahia hāora matū koiora (BOD) me te hiahia hāora matū (COD) o te waipara, me te whakatutuki i te maimoatanga kore kino o te waipara.
Haunga ngā ara hangarau kua whakahuatia ake nei, kei reira ētahi hangarau hou e whai wāhi nui ana ki te maimoatanga wai para ahumahi me te kore tukunga. Hei tauira, mā te hangarau tioata mimiti ka taea te wehe i te wai para totoka-wai mā te mimiti i te wai i roto i te wai para kia tioata ai ngā tote i roto, kia puta ai. Ka taea e tēnei hangarau te tango pai i ngā tote me ngā matū kino mai i te wai para, ā, ka tutuki ai te whāinga kia kore tukunga.
Hei tāpiritanga, ko te hangarau whakaora rauemi te mea nui ki te whakatutuki i te kore tukunga i roto i te maimoatanga waipara ā-umanga. Mā te tango me te whakaora i ngā wāhanga whai hua o roto i te waipara, ehara i te mea ka taea anake te whakaiti i ngā tukunga waipara, engari ka taea hoki te hangarua i ngā rauemi. Hei tauira, ka taea te whakaora i ngā iona konganuku taumaha me ngā mea rauropi i roto i te waipara me te whakamahi mā roto i ngā tikanga hangarau motuhake hei whakatutuki i te whakamahinga rauemi o te waipara.
Hei whakarāpopototanga, he maha ngā huarahi hangarau hei rongoā i ngā wai para ahumahi me te kore tukunga, tae atu ki te hangarau maimoatanga ā-tinana, te hangarau maimoatanga matū, te hangarau maimoatanga koiora me te hangarau whakaora rauemi. Me whiriwhiri me te arotau i te whakamahinga o ēnei hangarau kia rite ki te āhua o te wai para me ngā whakaritenga maimoatanga, kia tutuki ai te whāinga o te rongoā wai para whai hua, penapena pūngao me te taiao-hoa me te kore tukunga. I te haere tonu o te whanaketanga me te auahatanga o te pūtaiao me te hangarau, e whakaponohia ana ā muri ake nei ka whakamahia ngā tikanga hangarau matatau ake i roto i te mara o te rongoā wai para ahumahi, hei whakatairanga i te kaupapa tiaki taiao ki tētahi taumata teitei ake.
